lWhen i received this I thought it looked great but unfortunately on the first use I was very disappointed. I filled the tray with my usual litter and left for work. On returning home I found that there was urine on the floor around the tray. I emptied and cleaned the tray and tested it with a a jug and a little water. The water seeps through the join where the top sits on the bottom. Thought I had found the perfect tray sadly not to be.
